Friedrich "Fritz" Karl Otto Wunderlich (1930-1966) was a German lyric tenor, famed for his singing of the Mozart repertory and various lieder. He died in an accident just nine days before his 36th birthday.

"Wunderlich quickly earned a reputation as the leading lyric tenor in Germany. His clear, strong voice easily filled an operatic hall, but he always retained a purity of sound and line that was equally well suited to more intimate settings... All of his performances were marked by an unflappable lyricism and an associated control of phrasing and breath, both of which have remained his most lauded qualities." - All Music Guide
